Sulfuric acid

An inorganic compound with the chemical
formula H2SO4, which is the most important oxyacid of sulfur. Pure sulfuric acid is a colorless oily liquid that crystallizes at 10.36°C. Its aqueous solutions of various concentrations are usually used and prepared by tower method and contact method. The former is crude dilute sulfuric acid, with a mass fraction of about 75%; the latter can be obtained with a mass fraction of 98.3% concentrated sulfuric acid, with a boiling point of 338°C and a relative density of 1.84.
